My buddy had his car tuned at zzp so he wanted a rematch. Needless to say it wasnt enough! They were really close runs though, I had about two cars by 120.





First roll was a 40, second was a 60, third was a 50, and fourth was around 50 as well.

nice runs man

 

I didnt know you ran e47 adam. Still nice pulls, to bad you aren't closer to see how the ko4+ and e47 compares to your car

Is the hhr an auto trans?

 

Nope he has an f35 g85

And thanks guys

 

Bump for views.

 

wow thats impressive, LE5 with 12 psi k04 vs a LNF with 25 psi k04. I never imagined that outcome. Id thought theyd be closer but maybe its the weight difference?

 

I do think weight is a big factor.

 

Nice runs man.

 

Thanks

Nice to see a racing video


Im guessing the higher compression ratio of the LE5 is a factor here. Considering how much more psi the hhr was running, and of course the weight difference.

Lol, michigan is right next to mexico dude.

 

He needs some E!

 

Haha i dont think he wants to switch, some people just dont like the hassle

 

No hassle. Theres a station with E right next to the walmart in big rapids lol

 

Nope, they took it out and put in ethanol free 90 octane gas.

We have to drive about 20 minutes south, and we keep a 55 gallon drum of it.

 

So he's only running 90octane? What are you running?

 

No i was just saying they replaced our ethanol pump with recereational gas.

He uses 93

I use 93/e85

 

I'm going to say that the factor is the fuel more then anything. The fact that your on e47 and he's on pump 93 mean you've got the ability for much higher timing than the LNF could think of. Put him on E47 and im sure itll be a closer run if not a different outcome. Just my .02 tho

robk

 

Im at about 18* of peak timing at wot

You dont think him running twice as much boost as me makes a difference? Lol
